1 This invention relates to a pipe cutting, crimpingand beading machine; and more particularly ;to a machine for cutting, crimping and beading stovepipe.

The principal objects of the present invention are to provide a device for cutting off a stovepipe to the desired length and crimping and beading the pipe on one end; to provide a device for beading and crimping the pipe with one operation after cutting off the pipe without removal of the pipe from the machine; to provide a device of this character having parallel housing arms for shafts carrying the beading and crimping rollers and having means for preventing undue spreading of the arms during the crimping and beading operation; to provide means on the device for holding a pipe for cutting in desired lengths; to provide means for adjusting the cutting-and crimping rollers; one with respect to the other; and to provide a device of this character simple, economical to manufacture and eiiicient in operation.

In accomplishing these and other objects,- I have provided improved details of structure the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a side elevational view of the device.

Fig. 2 is a longitudinal sectional view through the arms and crimping and beading rollers, particularly illustrating a pipe on' the lower arm in engagement with the cutting rollers.

Referring more in detail to the drawings:

I designates a pipe cutting, crimping and beading machine embodying the features of my invention, comprising a frame 2 having a standard 3 and base 4 for mounting upon a support (not shown) by bolts or the like 5. The frame has upper and lower spaced housing arms G and I in which are rotatably m u ted h f s 8 nd and respectively, driven simultaneously by a crank it) having a handle ll through gears (not shown) contained in housing 12 on the end of the frame, the crank being fastened to the end of the shaft 9 extendin through the housing as is the usual custom.

The upper housing arm 6 is provided on its outer end with a housing I3 for a bearing I4 surrounding the shaft 8 for spreading the shafts 8' and 9 as desired, the upper shaft 8 being mounted in the housing arm to move upwardly and downwardly. The housing [3 is provided with a boss [5 having a central bore opening i6 adapted to receive a threaded pin IT. The pin I1 is provided on its lower end with a flange [8 adapted to engage in' a groove [9 of the bearing '4 as best illustrated in Figs. 2 and 3. The upper efid of the pin I! is provided with a stop 20 carry ing' a handle 21 for operation of the pin for adj'usting the upper shaft with respect to the lower shaft.

The shafts 8 and 9' are provided with shoulders 22 and 23 respectively and mounted on the shafts and against said shoulders by keying or other Suitable means are cutting wheels 24 and '25 for cutting the stovepipe 26 to a desired length as best illustrated in Fig. 2.

Mounted on the. outer end of the shaft 8 is abeading and crimping roller 21 provided with a bearing sleeve 28 so as'to rotate freely on the shaft, the roller being held on the shaft by a nut 29. Also mounted on the lower shaft 9 is a' beading and crimping rol1eri3li which is keyed or otherwise rigidly secured to the shaft and held in place thereon by a nut 3|. The rollers 21 30' are provided with longitudinal ribs 32 with grooves" 33 therebetwe'en as is the usual practice for crimping pipes or other objects. The outer end of the roller 2'! is provided with an annular groove 34 which is adapted to receive a rib 35 on the roller 30 to form the bead as will later be shown.

The housings l2 and l3 are provided with facing bosses 36 and 31 adapted to receive a rod 38 upon which a stop member 39 is adapted to slide for adjusting the length of the pipe to be cut. The stop 39 is provided with a depending arm 40 having a place face 4| against which the pipe engages and the lower arm 9 carries a scale or indicia as indicated at 42 and the stop is moved along the rod 38 and held in position by setscrew 43.

It is to be noted that the housing arm 6 is hollow as indicated at 44 to allow the shaft 8 to move away and toward the lower shaft 9 to separate the crimping rollers as shown in Fig. 2. In order to limit spreading of the housing arms 6 and 1, a hook 45 is provided which engages over the top of the upper arm housing 6 and has a depending body 46 extending below the lower arm and turned parallel with the hook 45 forming an arm which engages the under side of the lower arm 1 to limit the spreading of the parallel arms, the body being turned downwardly from arm 46 as indicated at 47. The boss 38 is provided with a lateral opening adapted to receive a setscrew 48 to hold the rod 38 in place. The boss 3'! has its outer end open to allow for assembling of the rod 38 in the bosses. The stop 39 is placed on the rod 38 by loosening of the setscrew 43, the stop slid over the rod and the rod placed in the bosses and setscrew 48 tightened" to hold the rod in place.

Operation of a device constructed and-assembled as described is as follows:

The stop' 39 is set at the desired length of the pipe to be out. With hook 45 removed, the pipe is placed over the lower arm of the machine with its inner end engaging against the face 4! of the stop plate 39, preferably'with the stovepipe seam just behind the cutting rollers 24 and 25. The upper shaft 8 is lowered by adjustment of the pin I! to lower the cutting roller 24 until it pierces the stovepipe. The pipe is then severed completely by turning of the crank which causes the stovepipe to roll against the cutters. The top cutter is then raised so that it passes over the seam on the pipe and in passing it will cause a slight crease. The pipe is then taken out of the machine and bent slightly on the crease to snap the pipe where it is seamed.

To crimp and bead the pipe the stop plate is moved to the left as far as possible and the thumbscrew 43 tightened. The hook 45 is then placed over the two arms to eliminate the spreading of the arms. The pipe 26 is then inserted against the stop plate and the adjusting pin I! is then turned to bring the top rolls down so that the crimping and beading rollers 21 and 30 will engage the end of the pipe as illustrated in Fig. 3. The crank I0 is turned back and forth as the adjusting pin is tightened so as to effect mesh engagement of the ribs 32 in the grooves 33 of the rollers. The handle is then turned until the crimping rolls have crimped all the way around the pipe except the seam. The annular rib 35 on the lower crimping roll will engage in the annular groove 34 on the upper crimping roll to form the bead 49 on the pipe 26 as the crimping 50 is effected on the end of the pipe. The adjusting pin may then be turned to raise it upwardly to disengage the crimping rollers from the pipe.

It will be obvious from the foregoing that I have provided an improved cutting, crimping and beading device for stovepipe which measures, cuts and crimps and beads the pipe in two operations.

What I claim and desire to show by Letters Patent is:
